FKM / Viton™

Fluorocarbon (FPM, FKM, Viton™)

Fluorocarbon is a well- known high
performance rubber, and especially it has excellent resistance to high
temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids,
aromatics and many organic solvents and
chemicals.

Standard FKM compounds are
Bisphenol cured. FKM compounds with peroxide-cured possess better acid solution
resistance than the bisphenol cured, and can replace litharge-cured applied in
acid solution. In Some lubricants adding a few organic amide or amine, choosing
peroxide curing system Viton™ will be better than bisphenol curing system.

Other Common Variations

•FKM can also be submitted for approval to
Underwriters Laboratories (UL) for use in applications as prescribed in UL157.
•FKM has excellent resistance to high temperature,
oil, solvent, flame, chemical and weather, and it is usually applied in
automotive, chemical processing, aerospace and many industrials.
•Viton™ GLT is broadly used in
thermal range of -40℃to +250℃and it has outstanding resistance to aggressive HTS-type oils which are
commonly used in aerospace industry.
•Viton™ ETP is usually applied
in chemical industrial.
•In some fuels adding several methanol, Viton™ F and B-type are more usable than A-type especially F-type. If it
requires lower temperature, GFLT and GBLT will be available .
